MORTIMER CAHILL, OF CHICAGO, ILLINOIS.

HYDROCARBON STOVE-HEATER.

SPEGIFIGATIQN forming part of Letters Patent No. 683,723, dated October1, 1901.

Application filed September 1'7, 1900. Serial No: 30,291. (No model.)

To all whom it may concern:

Be it known that I, MORTIMER CAHILL, a citizen of the United States ofAmerica, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inHydrocarbon Stove-Heaters, of which the following is a specification.

My invention relates to certain improvements in hydrocarbonstove-heaters, the object being to produce a simple, cheap, andeffective heater which may be readily attached in an ordinary stove.

To such end the invention consists in certain novel featuresof-construction, a description of which will be found in the followingspecification and the essential features more particularly pointed outin the claims.

The invention is illustrated in the drawings furnished herewith by meansof three figures, Figure 1 being a perspective view of the device; Fig.2, a vertical longitudinal section of the same, the plane of the sectionbeing indicated at 2 2 in Fig. 1; and Fig. 3 is a side View of a hollowplug used in the generating-chamber.

In the views, Arepresentsacap, into which is fitted a hollow plug 13,formed in its outer face with a zigzag groove 1), beginning at b,continuing almost around the surface of the plug,and terminating at b inan opening leading into the interior thereof. The plug is closed at theend 11 A supply-pipe 0 leads from a reservoir or other source of supply,preferably located above the heater, so as to allow the gasolene,kerosene, or other hydrocarbon oil to flow into the heater, its endbeing threaded in the cap A and communicating with the end I) of thegroove 1). Into the top of the cap Ais threaded a nipple d, from whichleads a U-shaped pipe D to a T-coupling d, connecting the latter with asecond pipe D, which is plugged at its end. A pipe E leads from theT-coupling cl at right anples from the pipes D D and connects them totwo pipes F F by means of a second T- coupling f, the free ends of thepipes F F being also plugged, as shown in the drawings. Apertures f fare formed in the pipes F F and are adapted to direct the flame of gasupon the pipes D D, the heat being communicated to thevaporizing-chamber and causing the oil to become vaporized in the same.

In the operation of the heater the oil is permit-ted to flow slowlythrough the zigzag groove into the vaporizing-chamber, the cap and plughaving previously been heated sufficiently to cause the oil when itstrikes the end 11 of the plug to vaporize and flow through the tubes D,D, E, F, and F and out through the apertures f f. The gas when lightedproduces intense heat, heating the stove, and the flame being directedupon the pipes D D keeps them hot. A portion of the heat is transmittedto the cap and plug and vaporizes the oil as fast as it reaches theVaporizing-chamber.

I claim as new and desire to secure by Letters Patent-- 1.Ahydrocarbon-burnercomprisingavap- 7o orizing-chamber and communicatingwith a suitable source of supply, a zigzag passage surrounding saidchamber for conveying the hydrocarbon oil to the chamber, a pipe leading from said chamber, a second pipe con-' nected to said pipe betweenits ends and a pipe connected between its ends to the secondnamed pipeand formed with apertures adapted to direct the flame of gas against thefirst-named pipe; substantially as described.

2. Ahydrocarbon-burnercomprisingasupply pipe, at vaporizer connectedtherewith made up of a cap and a hollow plug having a recess betweenthem connected at one part with the supply-pipe and at another with the8 5 interior of the plug, and a pipe leading from the interior of theplug provided with orifices directed toward the vaporizer; substantiallyas described.

In witness whereof I have hereunto set my hand, at Kirkland, in thecounty of Dekalb and State of Illinois, this 1st day of September, A. D.1900.

MORTIMER GAHILL.
